MOTOR-mow.

'Patented May 7, 1907.

Application sied November 28,1904. seau No. 234,665.

To all whom it may con/cern.

Be it known that I, ALBERT MIERsCH, a subject of the .German Emperor, and residing at Breslau, Germany, have invented certain .new and useful Im rovements in Motor- Ilows, ofwhich the fol owingis a specification.

My inventionrelates to improvements in plows driven by explosive-engines'traveling with/the plow over the field, and is more particularly ada ted for gang-.plows, though 'also applieab e to those of the single-share t We. i

' The object of this invention is to provide a plow in which the shares are so arranged be-4 tween the front and. rear axles of the frame that both axles/are equallyweighted, that is, the downward pull upon theframe caused by the inclined shares entering the soil, will be taken up equally by the axles. The low shares being vertically adjustable in the frame, this pull upon`the frame will be varied according to the number of shares and the depth to which they enter the soil.

My invention is illustrated` in the accompanying drawing, in which Figure l shows a plan, and Fig.v 2 a side :elevation of the new plow.

The frame a, which carries the explosiveengine m and the plow made up of a triangular frame carrying shares b', is mounted on three wheels. The front Wheels c d have a common axle, which is driven 1n well-known manner by the engine, and rests in stationary -lies between the two axles.

bearings,while the hind wheel e turns pivotally with its bearings. The wheel c runs on the land,l while d and e run in the furrow. I

The plow is mounted with capability of vertical adjustment and of ready removal, in the suitably shaped part of the frame which In the particular form of plow illustrated, this adjustable plow body having uniformly distributed dotted lineswhich pass over the pulleys lc, l

and can be lengthened or shortened by i means of the ver n and handwheel o, accessible from the ldrivers perch p. The chainf is for' this purpose secured to the pulleyi mounted on the shaft 1*, and the chains g, h,-

to the pulleys k, Z'mounted on the shaft W, while t1 e pulley R, mounted on the latter shaft W, is connected by achain K with a drum s mounted on the shaft V, the toothed wheel t of which drum meshes with th'e pinion o mounted on the shaft' u, so that by throwingl 'over the lever n and turning the hand-wheel o in one direction or the other,`

the chains are caused to wind up or unwind 1espectively,'whereby the plow is elevated or sunk, that is to say, its shares caused to leave the ground ordescend to it.

vNaturally thel shares may also be vertically adjusted, to suit the character of the soil, during plowing if desired; and plowing may be started withf' out the furrow-wheels being first adjusted. The bars w secured to the outside of the `frame impart the necessary guidance to the plow-body so that the shares are prevented from vibrating. The hind-wheel e is turned by the spindle accessible from the perch p,

themotion being transmitted by a chain y to g the pivoted frame 4z which carries the bearings of the wheel e.l

The main shaft A of the engine m drives the counter-shaft B, from which, again, the

axle of the front wheely 1s driven. The method of mounting the plow between the two axles has the advantage that on the shares entering the groiind, a uniform pull is exerted on all the wheels, which pull is increased or diminished depending upon the depth to which the shares enter the soil, so that it regulates the friction of the wheels necessary for the utilization ofthe engine power. Since the plow is removable, the

full power of the engine can always be utilized, in so far that plow-hodies with a greater or less number of shares may be used, depending upon the nature of the soil.

It must be understood that I in no wise desireto restrict myself to the recise details of construction shown, as t ese may be greatly varied without departure from the essential features of my invention.

What I claim is zy A motor plow comprising a rectangular main portion, wheels and axles su porting it, a triangular extension'frame at t e front of the motor frame, a swivel wheel supporting the front of the-triangular extension, a body frame vertically uided .on the motor frame, independent pul eys carried bythe motor IOO immo at front and mail' respectively, chains In tvstimony whereof I afiix my signature attached to the body frame :uid secured to in presence of twowitnesses.
